Monitoring Energy Consumption at Gas Stations: Clearly Showing Cost Savings
In a bid to help plant operators reduce their energy consumption and costs, Grundfos, a leading pump manufacturer, offers a free 'Energy Check' for assessing the efficiency of circulation pumps. This service, conducted by specially trained employees, follows ISO 14414 (Energy evaluation of pump systems) and has a calculative accuracy of +/- 10 percent.
The Energy Check is particularly beneficial for plant operators as it provides a reliable estimate of the savings potential of the pumps. Martin Hofmann, Aftermarket Sales Manager at Grundfos, affirms this, stating, "The Energy Check offers a reliable estimate of the savings potential of the pumps."
During an Energy Check, the operator only needs to provide operating information for the assessment. Depending on the plant, Grundfos may take a closer look at selected pumps to achieve more precise results with more detailed information and calculate various alternatives. The calculated payback time for the exchange of circulation pumps in most cases is less than three years.
The Energy Check report includes essential data on the pumps examined, exchange recommendations, and key figures such as savings in electricity, energy costs, and CO2, as well as investment costs for modernization and amortization. In most cases, there are more efficient alternatives for almost all pumps during an Energy Check.
The quantified CO2 savings are becoming an increasingly important criterion for plant operators and service providers. For instance, in a hospital, an investment of around 47,000 euros for the exchange of 12 medium-sized circulation pumps opens up annual savings of 25,000 euros, resulting in significant CO2 reductions. Similarly, in an office and residential building, exchanging four outdated primary circulation pumps in the cooling system saves over 26,000 euros per year, contributing to substantial CO2 savings.
Moreover, the Energy Check is not limited to specific industries. It has been conducted more than 1,000 times per year in the German-speaking region, usually at larger objects with numerous pumps. For example, in a fitness center, two intelligently controlled block pumps instead of three outdated pumps running continuously reduce operating costs by almost 7,000 euros per year.
It's worth noting that if a partial modernization is already planned, the corresponding plant parts can be spared or decided on a case-by-case basis during an Energy Check. However, in most cases, an immediate exchange is usually recommended for pumps that are still in operation.
After the Energy Check, Grundfos discusses the results with the plant operator and provides further recommendations. This collaborative approach ensures that plant operators can make informed decisions regarding the exchange of pumps, even when the modernization is not due for another two years.
In conclusion, the Energy Check offered by Grundfos presents a valuable opportunity for plant operators to reduce their energy consumption, costs, and CO2 emissions. By taking advantage of this service, plant operators can not only improve their environmental footprint but also boost their financial performance.
